2 .

package com.qf.demo7;// OKHttpClient  postimport java.io.IOException;import okhttp3.FormBody;import okhttp3.OkHttpClient;import okhttp3.Request;import okhttp3.RequestBody;import okhttp3.Response;public class Test3 {    public static void main(String[] args) {        String path = "http://localhost:8080/Day28_03/LoginServlet";        // 2 创建okhttpclient对象        OkHttpClient client = new OkHttpClient();        RequestBody body = new FormBody.Builder().add("useName", "addd").add("pwd", "123").build();        // 3 创建请求方式        Request request = new Request.Builder().url(path).post(body).build();        // 4 执行请求操作        try {            Response response = client.newCall(request).execute();            if(response.isSuccessful()){                String string = response.body().string();                System.out.println(string);            }        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }    }}
